Problems solved by technology

However, this method itself still has a major deficiency, that is, the level of virtual prototype design is low, and it cannot provide support for the early stage of design requirements analysis, program design and evaluation, so the early requirements analysis, program design and evaluation are still is document driven

Embodiment Construction

[0039] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0040] attached figure 1 The upper layer is the virtual prototype of the flight control system, and the lower layer is the physical prototype of the flight control system; the virtual prototype layer is divided into a conceptual prototype of the flight control system based on SysML and Simulink description, and a flight control system realization prototype based on the integration of various single-domain models based on soft bus technology two floors. It can be seen from the figure that the full design cycle virtual prototype builds a bridge between the design requirements / ideas and the final physical prototype, thus ensuring the synchronization and consistency between the two.

[0041] The conceptual prototype is the upper layer of the full-cycle virtual prototype, corresponding to the system engineering design stage. It casts aside domain limitatio...

Abstract

The invention discloses a design method of a concept prototype of a flight control system, which belongs to the technical field of design of the control systems. The method comprises the following steps: step 1) carrying out demand analysis, management and confirmation on the flight control system; step 2) carrying out system analysis and confirmation on the flight control system, and carrying out structural and functional division on the system; step 3) designing all member simulators of the flight control system; and step 4) carrying out system level design and simulation on the flight control system, and establishing the concept prototype of the flight control system. The seamless butt joint between Rhapsody software and Matlab software can be realized by utilizing the point-to-point way, and design data in the two types of software can be organically combined. Compared with the prior art, by adopting the method, the correctness of the design of the flight control system from a top layer can be ensured, and the design efficiency of the whole flight control system can be greatly improved.

Description

technical field [0001] The invention relates to a design method of a flight control system, in particular to a design method of a concept prototype of a flight control system. Background technique [0002] The flight control system is a typical complex reactive system. The traditional flight control system design method is a document-driven design method. Its typical disadvantage is that the designer cannot perform operational evaluation on the design scheme before the system engineering physical prototype is manufactured, resulting in The ambiguities and errors in the design plan, and the cost of these ambiguities and errors not being discovered and modified until the system is later integrated is huge. [0003] Digital design is a sharp sword to solve the shortcomings of traditional document-driven design methods. Its technical connotation is to eliminate the ambiguity and errors in design schemes and decision-making by constructing a system virtual prototype and performi...
